SocketCAN Driver
The SocketCAN is based on the Linux operating system, and it contains the implementation interface of the network stack and the hardware driver. The hardware manufacturers program the hardware driver for the SocketCAN, and the network stack provides the standard BSD Socket APIs for users. Therefore, from the users’ point of view, they can easily and quickly program their applications without being familiar with the various APIs of the different hardware interface through the SocketCAN network stack.
Features:
Support Linux kernel version 2.6.31~2.6.34 (x86 hardware platform only).
Provide CANopen/DeviceNet master static library.
Standard interface for SocketCAN package. Users can use extended BSD socket APIs, you can program the CAN application as building a socket program.
Support Virtual CAN interface. Users can map several virtual CAN port into one physical CAN port. Each virtual CAN port has its own socket. Through these sockets, users can build the multi-thread application more easily.
Provide the RAW socket, CANopen master and DeviceNet master demos.
Good price-performance for economical applications.
